Good To Know

Q: Does this head gasket require new head bolts? A: Yamaha marine head bolts are typically torque-to-yield and should be replaced during reassembly. Always follow the factory torque sequence for the 1.8L engine.

Q: Can I reuse this head gasket after installation? A: No, head gaskets are single-use items and must be replaced any time the cylinder head is removed. Reinstalling a used gasket risks compression leaks.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
